This Internship represents an organizational hand on experience in Networking and

Security. The main objective of the report is a summary of gaining knowledge and

practical working experience about Network Device & Server configuration and

maintenance for the IT Department at Amin Mohammad Group. For any kind of user

requirement in the organization, I have to work with many different Network Devices

such as Switches, Router, Firewall, Wireless Access Point, Media Converter, Gateway,

etc. Also for a different kind of service, I have to work with Servers like DNS, MAIL,

PROXY, WEB, DATABASE, etc. Working with Amin Mohammad Group is a great

experience in Configure and Troubleshoot problems in Network Devices and Severs.

In there I got a chance to gather knowledge to deal with a technical problem and give a

smart solution with my skill. In my internship period, there are many things I achieved

from the organization and I think in the future it will help me to work with any other

organization professionally.

CHAPTER 1

INTRODUCTION

1.1 Introduction: Nowadays every device is connected through Networking. All type of communication

and every data transfer on the internet is a part of Computer Networking. All of the

things can do on the internet as Accounts Transaction or Fund Transfer, Weather

Update and many more happening in just a few seconds. For this type of

communication, there is a need to be strong data connectivity and Powerful Bandwidth

of Internet Connection. To use this technology people, need some support from Experts

who have deep knowledge about Information Technology. Because A system needs to

be monitored and maintained all the time for better performance and to stealthy. Also,

a lot of attack from hacker can interrupt the daily basis work on an organization System

which need to analysis, detect, and prevent the system by IT Expert. In one way we can

say an IT person's responsibility is to secure and maintain the System and Network

Devices of an Organization. Internship on computer networking focused on how to

maintenance and face troubleshooting for network devices.

1.2 Motivation: Computer Networking has become the most important part of our life. we cannot think

about our daily communication without any social platform and all those social

platforms connected via networking. Now without the right networking of a system, it

cannot work properly, and also it needs to be maintained regularly. because networking

devices and system servers cannot be worked alone and they need instruction, security,

monitoring, and maintenance by an Administrator (Network or System). working in IT

can be more challenging than it looks, cause any disaster can make it worse for an

Engineer.

Through Computer networking, not just some computer devices connected here, there

are a lot of devices (or nodes) like Laptop, Printer, IP Camera, IP Phone, Smart Door

Lock System, many kinds of Servers. So for an organization more or, fewer devices can

be connected in the network and all devices in the network should be working fine. This

is the primary responsibility of the IT department. Here I got my motivation for an

internship working with IT to become a Network Administrator. As a Network


Administrator there some responsibilities like Monitoring NOC, ensure the security of

the device in the network, and many more. and that responsibility highly motivates me

to work in IT. so that my Internship can be more useful when I use my skill and

knowledge to implement in the organization and make me more compatible for my

future career.

1.3 Internship Objective: Information Technology has become more helpful to business growth and it’s evolving

day by day. Technologies using smart devices for networking and security to share

information efficiently. Devices like router, wireless Access Point, controller, switch,

firewall, gateway are the main focal point in my Internship. That device has some

features which are done by the manufacturer like CISCO, MIKROTIK, DELL, etc. This

internship is gone through our knowledge of what and how the device can perform in

the real world. The Main Goals are following-

Achieving Knowledge about Networking Devices like a router, switch,

firewall, gateway, etc.

Design a Network like LAN, MAN, and also WAN for Large Organization.

Installation and Maintenances of Networking Devices.

Configure and Monitoring System Server through Networking.

Establishing Connectivity to Remote from Head Office.

To Secure the network for any private data transmission from one office to

another via VPN.

Conceive the knowledge about Server Administration as per needed in the

organization.

1.4 Introduction to The company:

As per my objective of Networking and security to build my knowledge and skill I

choose my internship with Amin Mohammad Group under the IT Department. This

organization has done many businesses like real estate, development, and

telecommunication through activities of Information Technology.

The IT department of this organization heavily relies on it to get sharing data and

important information across essential channels. There is an overall 50 plus project over

the nationwide and online activity maintained by the IT department. All the projects are


covered by CCTV and the organization has its Own Network Data connectivity over

all the Bangladesh through different ISP providers. The Company's business work

process is also done in Enterprise Resource Management System which also develops

and maintained by IT & MIS.

CHAPTER 2

ORGANIZATION

2.1 Introduction: As an internship for Networking and security, I have joined the IT Department of Amin

Mohammad Group. Besides every other Organization, I choose Amin Mohammad

Group because this organization has a good environment for learning my required

skills. The Company has many activities through information technology like High

Bandwidth Internet Connection with Redundancy, Enterprise Resource Management

System, Wi-Fi Coverage for whole H/O office, All Project under Data connectivity,

CCTV coverage for all offices and playback from anywhere, Network Area Storage for

dynamically backup files, VPS Hosting Mail Server, etc. To ensure maximum

efficiency and productivity for the organization the management has taken all over the

thing to the digital system. There are different kind of servers which has used for a

different purpose, those servers are Zimbra Mail, Apache, SQL, DNS, AD, Cache, ERP,

Hosting, Antivirus, etc. The whole organization network is secured and it has good

management for building the organization and its people career.

2.2 Product and Market Situation: As for the different type of Network user’s requirement and remote location servers

Amin Mohammad Group have using updated technology. In my internship period, I

have work with many devices for networking as storage, the network for a wireless

system which is manufactured by a different company, and the product has a smart

feature for any kind of task. Networking Devices of Cisco, Microtik, Sophos, Juniper,

Qsan are essential technology solutions for the organization. Networking devices also

include inexpensive setups to anywhere and maximum utilization of available resources

done within any time.

There also Servers manufacture by Dell, Hp, IBM that are deliberately used for

multipurpose. The servers are customized for services and privileged with security to

protect them from any kind of outsider. Information Technologies has to face some real

issue into the global market, the new product is always being updated and a new version

of any software or application need to be also updated. The more an IT Engineer of an

organization updates his system with global the more they will be a chance to survive

in any situation.


2.3 Target Group: The Organization always need to be set a group of targets and need to accomplish the

targets with all dedication. In my internship organization, all of the targets were

distributed to every level of management employee. As per the IT department, the

targets are to accomplish more with technologies to future.

2.4 SWOT Analysis: By SWOT analysis a business can have more development than before. SWOT analysis

means that a company’s four things which are strengths, weaknesses, opportunities, and

threats. The main objective of this analysis is making a business decision to help the

organization develop a full awareness of all the factors involved. I have to use swot

analysis for my internship company to recommendations and strategies, focusing on

leverage strengths and discover opportunities to overcome weaknesses and threats.

2.5 Organizational Structure: An Organization Structure is said to be a structured system where a hierarchy is run

within an organization. There can be any type of structure we can see in an organization.

My Internship Organization also has and structure from Top Management to officer

positions which are given below.

CHAPTER 3 TASK, PROJECT AND ACTIVITIES

3.1 Daily Task and Activities: An organization has some daily routine of work that needs to do on scheduled time.

The management of the organization has distributed work to every Department. As like

as IT department has dedicated task, activities for team members.

As for four months of internship in the IT department, I also have to work on the daily

task, activities as given by my instructor. My daily task was given weekly so I can gain

my knowledge and implement skills to the work step by step. Some activities when feel

to be difficult to me then my Instructor show me how to make the best decision at that

time. Also in my internship period, I have learned how to complete given tasks and

activities and report to the instructor daily. As per my Four-month internship period, I

have participated in daily task and activities which are given below:

3.1.1 First month of my internship I have learned about basic fundamental along with

lot of orientation and I have performed many tasks under the IT Dept. of Amin

Mohammad group which are briefly mention in following:

3.1.1.1 Network Components that used in the organization

In Computer Networking there is lot of device used in different topology for an

organization purpose. The components are mostly manageable so that engineer can

customize as per organization requirement. As an internship to the organization I

learned when and where which device we need to use for computer networking. In the


following I have demonstrated a short summary for the components that I have work

with:

• SWITCH: Switch is a multiport bridge along with a buffer that has working in

data link layer in the OSI model. It’s mainly forward the data one to another, in

the transmission of data it can check error.

• ROUTER: Router is a device similar feature like switch that work in the

network layer in the OSI model. Routers can transfer data from one network to

another using routing protocol.

• GATEWAY: Gateway can work in any network layer and its more than advance

from router or switch. It’s mainly work like transfer the data from one system

model after interpret it then it sends it to another system.

• FIREWALL: Firewall is a security device or software that uses for network

security and protect private network from any kind of breach which means

unauthorized access.

• Wireless Access Point: Wireless AP is a device that creates a WLAN aka

wireless local area network. Its create a portal for the user to the network

through wireless connection using. In the other side all the AP are connected to

a switch or router.

3.1.1.2 Networking Media

In Computer Networking the transmission media is the pathway for data transmission

in a network. We have used different types of cable or media to transmit data. There

are two type of transmission media one is bound transmission media which is cable or

physical existence and another one is unbound transmission media which without cable

using microwave or radio wave. In my internship company we have seen the uses of

this media in many sites for computer networking.

Figure: 2 Network Components Figure 2: Computer Networking Components

Figure 3: UTP & STP


Twisted Pair Cables: Twisted pair cable is two types; Unshielded and shielded. STP

is protected against electromagnetic interference(EMI) and UTP is not shielded against

EMI.

Co-axial Cable: Co-axial cable is a solid central conductor surrounded by insulating

materials and along with woven of cylindered shield of fine wires. It has broader

bandwidth and used for audio, video data transmission.

Fiber-Optics Cable: Fiber optics cable using its photons to transmit data, it is covered

with protected shield of central glass tube. Its free from EMI as well as wiretapping.

Radio Wave: Radio Waves transmit the data in process of a single or multiple

frequency.

Figure 4: RJ 45 Connector

Figure 5: Radio Wave


Microwave: It has higher frequency than radio waves and it can handle large amounts

of data.

Infra-Red: Infra-red communication uses light like fiber cable which offer great

unbound photonic solution.

3.1.1.3 Understanding TCP/IP Protocol and Ip Address Subnetting

In computer Networking TCP/IP (Transmission Control Protocol/Internet Protocol) is

used to interconnect network devices on the internet. it also used in a private computer

network and it known as a communication protocol suit. The entire internet protocol

suit is a set of rules and procedures is defined as TCP/IP, these are the two main protocol

beside many others. Table 1: Demonstrating TCP/IP Layer & Protocol in different Layers

3.1.1.4 L2 and L3 Switches and Switching concept

I have learned various features and application of switches at L2 and L3 of the OSI

Model. The basic concept of the L2 or Layer 2 switches use mac address and the L3 or

Layer 3 switch uses routing algorithm. I will demonstrate the concept of L2 and L3

switches with basic functionality.

Application HTTP FTP TELNET SMTP DNS

Transport TCP UDP

Network IP ARP ICMP IGMP

Network Interface Ethernet Token Ring Other Link-Layer

Protocols

Figure 6 Micro Wave


Table 2: Functional Different Between Computer Network Switch Layer 2 & Layer 3

Next-Generation Firewalls and IPS

A Next-Generation Firewall (NGFW) provides network security, functions with

intrusion detection (IDS) and intrusion prevention system (IPS). It’s part of third

generation firewall technology. Also next generation firewall includes like Application

and User Control and it also has Advanced malware detection such as sandboxing.

3.1.2 In the 2nd month of my internship I have learned and gained my skill about

the equipment and infrastructure of entire network that used in an organization.

This section I have described that how an IT Engineer fulfill its daily task and

activities on Cisco Devices like switch, router etc.

Know about VLAN and Configure VLAN

In this task I have configure VLAN in cisco switch. Before configuring VLAN we need

to understand the value of this. VLAN needed when there is multiple sub network and

different activities to apart from each other, like an organization department has

different activities.

L2 Switch L3 Switch

It’s basically operated on Data Link

Layer (Layer 2) of OSI Model

It’s operated on Network Layer (Layer 3) of

OSI Model

On the basis of MAC address it send

frames to destination

Using ip address routing the packet to

destination

L2 switch only work with MAC

address

It has combine feature of L2 and L3

L2 Switch has single broadcast domain L3 has multiple broadcast domain

Communication happens within

network

Communication happens within or outside

network.


Step 1: Now from the switch console cable we can enter its Command Line Interface

(CLI) so we configure VLAN. Now write command for enter into config mode

Step 2: Then we will configure a line console password for security purpose.

Step 3: Given command is for VLAN setup for specific Department or Identity (name)

Step 4: After VLAN specified we can assign the interface port or interface range to the

VLAN

3.1.3 In the Month Three I have gained very important part of my internship. In

this section I have discussed about Linux server and demonstrate about its very

basic part. Also the following part will be seen as step by step.

• Introduction of LINUX kernel.

• Installation of Linux CentOS 8.

• Managing User Accounts and passwords.

• User and Group Add and Modification.

• File and Directory creating, Control, and permission.

• Ownership, Group and User Permission.

• ACL Permission Configuration.

3.1.3.1 Introduction of Linux Kernel and Centos 8 Installation

The Linux kernel is a free software (also call open source), it has multitasking similar

as Unix OS kernel. It is the main component of Linux operating system and its the core


interface between a computer hardware and its process. Linus Torvalds first created and

introduce the concept in 1991. Linux kernel operating system is called Linux

distribution that provided free.

CentOS is a community supported platform Linux distribution that compatible for its

upstream source with Red Hat Enterprise Linux (RHEL).

Most of the software is free and open source software available in internet both as

compiled binaries and in source code which allow to modification to the original

software.

Now Centos 8 Installation can be done by two methods, one in personal computer either

duel boot or single and other one is at virtual machine application like Oracle Virtual

box or in VMware workstation. I am using VMware workstation pro 15 for installing

Centos 8.

Installation Process > After system completed loading the boot media, the boot menu

will display Grand Unified Bootloader (GRUB2). Then using arrow key to selecting

the Install Centos 8 option and press Enter.

Figure 7: CentOS 8 Installation


Now from the Installation Summary need to configure installation source, software

selection and finally partition the hard disc.

In Localization Keyboard will set as English(US), Language as English(US), Time &

Date Time zone will be Asia/Dhaka.

In software selection I am selecting the Server with GUI >

Figure 12: Installation Begin


3.1.4 In the Month Four of my internship I have learned the Apache Web server.

This server has various type of configuration and most of Web server we see are

based on this. I have demonstrated step by step my learning things in following.

• Installing and Configuring Apache Webserver on CentOS 8

• Checking Webserver

• Managing Apache Process

• virtual Hosting on the server.

• Adjusting SELinux Permissions.

3.1.4.1 Installing Apache Webserver

CentOS software or package repositories by default available name Apache, dnf the

software package manager that provides the install, remove or updates are needed for

packages based on rpm.

The installation command for http server:

• For secure http service we need open up the HTTPS 443 port permanently.

• into effect the new rules firewall need to reload

3.1.4.2 Checking Web Server status Initially the web service (httpd) does not start its process after the installation. So we

will start the httpd process with following command by manually:

• Also on CentOS start the httpd.service stayed disabled. We need to enable it

for by default start the process on OS start:

• The status after enabled the httpd service

By default, its disabled


Now with the ip address http://192.168.122.1 of server’s it shows default index of

CentOS 8 an Test web page:

3.1.4.3 Managing Webserver

Apache configuration files structure and how to Manage it as a System Administrator.

• Directory has the All Apache configuration files.

• Although the main configuration file of Apache is here

• Configuration files end with .conf which located in the directory and it contain

3.1.4.4 Virtual Hosting for Webserver

We can use virtual hosts to encapsulate configuration details and from a single a server

we can host more than one. Now I am setup up a domain called

as we know by default one virtual host is enabled in which is configured to the directory.

It can work as well for one single site, but it can be difficult for

hosting more than several websites.

Instead of modifying here we are making new directory within

for the web as website,

Figure 14: HTTP Web Server view


unchanging the directory as it is will be default so if a request from any other site won’t

match.

Creating the html for directory as follows

Creating the log for domain as an store log log for the site:

Then need to assign ownership for html directory with $root environmental variable

Default permission for root, so it can access web

Then using vi editor, creating as a sample for index.html page.

in INSERT mode of vi Editor we are going to add the following html code:

by a sites-available as a directory it will uses for store the virtual host conf files.

And also need to making site-enabled directory so that it can acknowledged the server

that it’ll be serve by a virtual host to the given visitor. Now as for virtual host to publish

a symbolic links will hold for the directory of the sites-enabled.

Then web service need to look for virtual hosts which is situated at the sites-enabled

directory. To gain this, we need to include the command in main config of Apache’s

using vi editor.

Now in vi Editor we will insert the command at end of the file as follows:


After saving the file we have virtual host directory in place and finally we need to create

the virtual host file. So we will create the file in sites-available directory:

And then we have to define and show our domain configuration directories and files

path into the ‘.conf’ file. As for documents which publicly accessible by root direcly

should be acknowledge by web server. And it will also tell the server as in where the

particular site log for error and request are located:

The virtual host file now need to enable so that apache knows that its ready for serving

to them. For every virtual host that are in sites-enabled directory that we need to create

a symbolic link:

3.1.4.5 Adjusting the SELinux Permission

SELinux is a kernel security module. We use it for heightened the security for any Linux System. SELinux is configured by default to operate it’s process the web service with default config on CentOS.

For setting up a custom made log directory in the virtual hosts configuration file the default configuration has been changed. For that reason, we will get error in attempting of Starting the httpd. Determine this, we can allow the required files by updating the SELinux policies.

SELinux permit to change its security level by given the necessary setting policies are in based on environments need. Since there are many ways to setting policies, now I will illustrate two method of adjusting policies, one is universally and another is on a specific directory.

• Universally SELinux policies

It uses the Boolean name http_unified so that SELinux act towards all the web server process identically


• On a specific Directory

This will set an individual setting of SELinux permission for directory, which can more

control over the Apache policies. In the virtual host configuration, a context type should

be modifying in newly log directory.

httpd_sys_content_t was current context and after changing the context type of the

log directory it will be httpd_log_t. this type will allow web service to generate and

append

Checking the Virtual Host for Webserver

3.2 Event and Activities

During the internship period, I have to work regularly to complete my achievements.

For a different type of requirement in the organization, we need smart plans and

different methods to apply in the system. A System can give its output efficiently and

productively when it's organized and managed through well planned. Without planning

or managing any problem can arise and that particular can be a nightmare for IT

Engineers. We need to be more active in such events and properly work on activities.


In IT dept. of AMG I have active with many events and done activities which are given

below.

3.3 Project Task and Activity

Since the start, an Organization develops its business day by day for a better future. A

company always needs to work on the project and complete it to make an organization

a better portfolio. Projects are distributed to management for accomplishing the target

in due time. The project director distributes the task to the project manager and to the

manager it goes to the team coordinator and member as follows.

As an internship, a project has been assigned to me, and I have work on the project task

and doing some regular activity. I have designed an SNMP server for my organization.

Simple Network Management Protocol as known as SNMP is a protocol that used for

health or welfare monitoring of network equipment like a router, switch or any device

that connected. it is mostly used in a large organization computer equipment and even

devices like UPSs. Following are my project task and activity are given.

To know about the SNMPc Enterprise Application.

Installing the SNMPc v 7.0 Enterprise Server

Configuring the Local Console Session

Then design required Network Area in graphical view

Configure the device and connected to the core network.

Also, connect the pc or server to SNMP

3.3.1 To know about the SNPC Enterprise Application.

The SNMPc Enterprise is used for secure an organization distributed Network Management System which delivers approximately real-time monitoring. Product key features are:

Monitoring SNMP Devices on the network, wan/lan links through devices, servers, and devices on the network.

This application support SNMP v1, v2c, and secure SNMP v3.

The status of the server will be shown live/standby in automatic failover.

Automated Network Discovery.


3.3.2 Installing the SNMPc Enterprise Server and Local Console

Run as Administrator the setup.exe file of SNMPc Network Manager.

In the dialogue box, we have to choose SNMPc Enterprise and choose Server button.

In the next, it will show a Discovery Seed dialog will be displayed.

There we have to put IP of a seed device (router, switch, server) on our network.

Figure 15: SNMP Server Setup

Figure 16: SNMP Setup Process


And then we have to put subnet mask for seed device.

For the Seed Device we have to enter v1, v2 or public into community

The SNMPc program installation is finished. Now After Restart we can use it for configuration.

3.3.3 Configure Local Console Session

Start from windows menu the programs “SNMPc Network Manager” After a command box of Login Console Menu will appear. Initially the user name is default as Administrator with no password. We need disable the automatic console startup and login from task setup.

3.3.4 Creating Object of Network

Figure 7: SNMP IP Address Assign


From Side menu new object can be created, and it has to be defined and configured with ip addresses.

The Object Configuration for Network Switch or Router:

The Object Configuration for Server or PC in the network:

3.3.4 Design the MAP View

Map view window have all the object in the network. The objects are equipment like switch, firewall, router, gateway etc. the equipment is connecting with a pipeline to network from core router or switch.

3.4 Challenge

The Internship Experience at Amin Mohammad Group was great for me. The first time

when I join with the IT department for an Internship, I was not very comfortable with

my daily task and activities.

But I have adjusted with the help of my instructor and teams. In daily tasks sometimes
